VENDING-MACHINE.

Specification of Letters Patent.

Patented Nov. 27, 1906.

Application filed July 10, 1905. Serial No. 268,919.

the coin serves as a connector to insure the operation of the delivery mechanism.

The invention has for its object. the production of simple and inexpensive means for insuring the prompt delivery of an article upon deposit of the proper coin.

A further object is to provide means for preventing the surreptitious operating of the machine without the deposit of the proper com.

A further object is to provide means to prevent more than one operation of the ma chine upon the deposit of each coin.

With these objects in view the invention will be hereinafter fully described, and particularly set forth in the claims.

In the accompanying drawings, Figure 1 is a rear view of a vending-machine embodying my invention, parts being shown in section.

Fig. 2 is a side view thereof, parts being in section. Fig. 3 is a detail view of the coi1icontrolled mechanism after the same has are detail perspective views illustrating the coin-chute and its adjuncts. Fig. 7 is a front elevation of the yoke member in detail.

Fig. 8 is a top view showing the arms of the' yoke member in section, also the cam in said yoke member and the pivoted lever engaging said cam. Fig. 9 is a detail view of the coinchute. Fig. 10 is a side elevation of the coinchute mounted on the shaft. Fig. 11 is a detail perspective view of the lever'that is pivoted 011 the shaft.

Referring to the drawings, designates a casing provided with an extension 21, in which the articles to be vended are located, and a chamber 22, containing the coin-controlled mechanism. The articles to be vended are preferably placed in cylindrical cartons 23 which are placed in a chute provided with a plurality of compartments 24 25, which communicate with. each other at their upper ends. The lowermost carton in compartment 24 rests upon the upper end of a yoke member 30, to be hereinafter described, the lowermost carton in compartment 25 resting upon a cylindrical member 26, supported by counterbalancing-weights 27, connected thereto by cords passed over pulleys 28 in the top of extension'21. By this arrangement the weights 27 serve to elevate the topmost carton in compartment 25, so as to automatically deliver the same into compartment 24 when the lowermost carton of said compartment 24 has been removed by the delivery mechanism.

The delivery mechanism comprises a yoke member 30, pivoted at its lower end in chamber 22, the arms 31 thereof serving to support the lowermost carton in chute 24. Said yoke member is held normally beneath chute 24 by means of a spring 32. Interposed between arms 31 and arranged transversely to the pivot of the yoke is an oscillating shaft 33, carrying a coin-chute 34 and provided with an operating-handle 35, said chute registeringwith an opening 36 in chamber 22. .Said chute is tapered, whereby the coin is prevented from passing entirely through, as shown.

On a reduced portion of shaft 33 is pivotally mounted a transversely-arranged lever 37, one end of which is provided with a protuberance 38, adapted to contact with a coin C, held in chute 34, the other end of said lever being provided with an extension 39 normally engaging a cam 40, formed on yoke member 30. 4

A spring 41 serves to return the shaft 33 and its adjuncts to their normal positions after operation.

On the coin-chute 34 is pivotally mounted a member 42, provided with a finger 43,pro jecting over the narrow end of said chute and adapted to enter the open side of the latter, the opposite end of said member being provided with a finger 44, adapted to engage a stationary cam 45, whereby the coin is forced out of said chute when the shaft 33 Said enlargement is-adapted to engagea lug 49 on yoke member 30, the arm 46 being under the, tension of a spring-50.

The operation is as follows: A coin upon 5 being deposited in chute 34 will be arrested in its movement opposite the protuberance 38 of lever 37. The shaft 33 is then: turned by means of its handle 35, the projection 39 of lever 37 riding over cam 40. The coin serves to revent the rocking of lever 37, as

will be 0 early apparent, and as a consequence the action of said lever on cam 40 forces the yoke member 30 to rock'forward -on its pivot. The effect of this is to permit I 5 the lowermost carton 23 in compartment 24 to drop on the top of chamber 22, and at the same time the spring 50 will draw the free end ofthe locking member 46 into engagement with lug 49, thereby locking the member 30 in its forward or abnormal position to prevent a second operation of said member before the deposit of another coin. As said shaft '33 continues to turn the finger 44 of member 42 engages cam 45 and the coin is thereby forced out of the chute. Just previous to this latter operation, however, the protuberance 38 of lever 37 engages finger 48 on the locking-lever'46 and depresses the same'below lug 49, whereupon spring 52 will 0 return the yoke member to its normal position. "The result of this operation is to cause the arms 31 to kick the carton off the topof chamber 22, whereupon said carton will fall to the delivery-opening 51. The 5 shaft is at the same time returned to its normal position by spring 41. It will be noted that if the shaft is turned when there is no coin in chute'34the cam Will force the protuberance 38 intothe open side of the 40 chute and the position of the yoke member 30 remains unchanged. As the carton from compartment 24 is dropped o-n'the top-of chamber '22 thecounterbalanced member 26 will simultaneously deliver the topmost car- 5 ton in compartment 25 to the-compartment '24, thus automatically replenishing the latter compartment.

The advantages of my improved vendingmachine will be at once apparentto those skilled in the art to which it appertains. It will be particularly noted that the parts are positive intheir operation, and thus insure prompt delivery of the vended article. It will-also be noted that the surreptitious op- 5 5 eration of the machine is effectually prevented.

It will be further understood that while I have shown and described my improved machine as adapted for the delivery of cylin- 6o drical cartons'I do not limit myself thereto,

as the same is equally-applicable for the delivery of'goo'ds of other character.
